The quality management of the machining industry is a very detailed and complex systems engineering, which is not detailed here. From the perspective of the customer, the high-quality precision parts include the following characteristics:

• Dimensions meet the drawing requirements.
• The mechanical properties of materials such as hardness, and yield strength meets the requirements of the drawing.
• Surface treatment such as electroplating meets the requirements of the drawings
• Good appearance and quality of the parts

 Concept identity

Our company agrees with the concept of quality first from top to bottom, carries out quality analysis and improvement activities on a regular basis, never ignores product quality because of busy orders, and resolutely does not send unqualified products to customers.

 Dimension guarantee for precision machining

In order to make the size of the precision machining parts meet the requirements of the drawings, the most important thing is that the factory needs to be equipped with advanced machining equipment, cutting tools, fixtures, and dimensional inspection equipment. Without advanced processing equipment, no matter how good the workers and management system can not guarantee the stable production of qualified precision machinery parts. We have a deep understanding of this. For this reason, we use most of the company’s profits on the purchase and update of machining equipment, cutting tools, and inspection equipment every year. At the same time, we also organize regular quality system training for employees to constantly improve product quality.

Material assurance of precision parts

The material of the parts is also a very important point for customers. We mainly guarantee the following three aspects:

• From the source to ensure the material, we purchase domestic large factories such as Baosteel, Hangzhou steel, and other production of steel, aluminum, and other metal materials.
• Heat treatment is also a very important link. We mainly cooperate with the leading heat treatment plants in the Ningbo area, such as Dashan heat treatment.
• Our factory is equipped with a spectrometer, metallographic analyzer, hardness meter, tension meter, magnetic particle flaw detection machine, and other inspection equipment, the company can do material composition analysis, mechanical performance testing, and non-destructive testing.
